well u as u have a couple of weeks, that is plenty of time for u to work on her. in order for you to get her really in to you, you must build attraction and rapport with her. attraction is fast with the right combination of positive and negative validation (push pull technique) i.e. if there's something u like let her know that u approve, if there is something u dont like about her show that u r not impressed. there's also negging and teasing as well. but these attraction techniques should be used depending on the type girl u r dealing with, these are purely for girls of high calibre (hb7.5 and up). but some men dont realize that u should use positive first and then negative validation on the girl because if u use the negative first then u will just end up hurting her and be perceived as an asshole.

there's also building rapport to emotionally connect with her, talk about things which have deep emotional content, being empathetic with her, imagine what it is like to be her, tell her how would u feel if u were her doing that activity or something. from this she would perceive u as someone who is really trying to understand her, someone who is deep and can have a great conversation with instead of trying to get into her pants lol.

women like men who are observant and situational. notice things about ur target, what she is wear (clothes, jewelry etc). so if u notice something about her (do not comment on how beautiful she is) tell her about it e.g. u notice her bracelet, when talking to her, take hold of her wrist gently and say "wow this is an interesting bracelet, whats the story behind it?", there's always a background story behind women\s accessories.

try and do ur game on her, probs get a date with her by the end of the week as long as u get her number (tell her to give u her number, dont ask).

Hope that i have helped. happy gaming dude
